问题描述

我目前正在尝试在 PHP、Mysql 文档中显示条形图，但遇到了一些问题。

1- 图表在小提琴上几乎可以正常工作，但在我的本地机器上却没有。 小提琴上的图表

这是我的图表示例代码：

    google.charts.load('current', {'packages':['corechart', 'bar']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {

  var data = new google.visualization.DataTable();
  data.addColumn('date', 'Data');
  data.addColumn('number', 'Valor de Renda');

  data.addRows([
   [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2010, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2011, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2012, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2013, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2014, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2015, 1, 01), 1500], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2019, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2020, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2021, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2022, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2023, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2024, 1, 01), 1000], [new Date( 2025, 1, 01), 1000],
  ]);

  var linearOptions = {
  axes: {
        y: {
            all: {
                range: {
                    max: 3000,
                    min: 000
                }
            }
        }
    },
    bars: 'vertical', // Required for Material Bar Charts.
    width: 800,
    height: 300
  };


  var linearChart = new google.visualization.LineChart(document.getElementById('linear_div'));
   linearChart.draw(data, linearOptions);


}

2- 我尝试使用小提琴中显示的数据，但页面上仍然没有显示任何内容。

3 - 示例数据在本地有效，但在我更改数据时无效

我的数据是从 Mysql 查询中收集的，我正在“回应”我应该在哪里：

  google.charts.load('current', {'packages':['corechart', 'bar']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {

  var data = new google.visualization.DataTable();
  data.addColumn('date', 'Data');
  data.addColumn('number', 'Valor de Renda');

  data.addRows([
   <?php echo $listagem ;?>
  ]);

  var linearOptions = {
  axes: {
        y: {
            all: {
                range: {
                    max: 3000,
                    min: 000
                }
            }
        }
    },
    bars: 'vertical', // Required for Material Bar Charts.
    width: 800,
    height: 300
  };


  var linearChart = new google.visualization.LineChart(document.getElementById('linear_div'));
   linearChart.draw(data, linearOptions);


}

更新：

AS 建议我尝试在查询中将数据转换为 Json 对象：

$rows = array();
$table = array();

$table['cols'] = array(
    array('label' => 'Data', 'type' => 'date'),
    array('label' => 'Valor', 'type' => 'number')
);


$query_old_date = "SELECT ContratoFraccaoInicio AS INICIO, ContratoFraccaoFim AS FIM FROM TbContratoFraccao WHERE FkFracao=" . $id_fraccao . " ORDER BY ContratoFraccaoInicio ASC";
$result_old_date = mysqli_query($link, $query_old_date);

while($datas = mysqli_fetch_assoc($result_old_date)){

    $old_date = $datas['INICIO'];
    $end_date = $datas['FIM'];

$data_inicio = date('Y-m-d', strtotime($old_date));
$data_fim = date('Y-m-d', strtotime($end_date));


$start    = (new DateTime($data_inicio))->modify('first day of this month');
$end      = (new DateTime($data_fim))->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$period   = new DatePeriod($start, $interval, $end);

foreach ($period as $dt) {
   $mes =  $dt->format("Y-m-d");




    $query_valor_mes = "SELECT MAX(Data) AS DATAVALOR FROM TbContratoFracaoPreco WHERE FkFraccao='$id'  and data<='" . $mes . "'";

    $result_valor_mes = mysqli_query($link, $query_valor_mes);

    while($row_valor_mes = mysqli_fetch_assoc($result_valor_mes)){
        $data_valor = $row_valor_mes['DATAVALOR'];




        $query_obter_valor = " SELECT * FROM TbContratoFracaoPreco WHERE FkFraccao='$id' and data='" . $data_valor . "'";
        $result_obter_valor = mysqli_query($link, $query_obter_valor);

        while($row_renda = mysqli_fetch_assoc($result_obter_valor)){

            $rent = $row_renda['ContratoFracaoPreco'];


            $date_year = date('Y', strtotime($mes));
            $date_month = date('m', strtotime($mes))-1;
            $date_day = date('d', strtotime($mes));

            $listing =  "Date(" . $date_year.", " . $date_month .", " . $date_day . ")";


                $temp = array();
  $temp[] = array('v' => (string) $listing);
  $temp[] = array('v' => (float) $rent);
  $rows[] = array('c' => $temp);



        };



    };
};
};


$table['rows'] = $rows;

$dados_chart = json_encode($table);

在图表中我有：

google.charts.load('current', {'packages':['corechart', 'bar']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {

  var data = new google.visualization.DataTable();
  data.addColumn('date', 'Data');
  data.addColumn('number', 'Valor de Renda');
  data.addRows(<?php echo $dados_chart;?>);

  var linearOptions = {
  axes: {
        y: {
            all: {
                range: {
                    max: 3000,
                    min: 000
                }
            }
        }
    },
    bars: 'vertical', // Required for Material Bar Charts.
    width: 800,
    height: 300
  };


  var linearChart = new google.visualization.LineChart(document.getElementById('linear_div'));
   linearChart.draw(data, linearOptions);


}

在空白页旁边，我唯一拥有的是这个控制台错误：

在此处输入图片说明

回显 $dados_chart 对象后的示例结果：

使用更新的 json 对象，
您可以直接创建数据表，
没有addColumn和addRows

换这个...

var data = new google.visualization.DataTable();
data.addColumn('date', 'Data');
data.addColumn('number', 'Valor de Renda');
data.addRows(<?php echo $dados_chart;?>);

有了这个...

var data = new google.visualization.DataTable(<?php echo $dados_chart;?>);
